CT is right. If the chips were made, NV gaming would never see them. No different than a riverboat chip in Iowa.
Could they produce an HCE or Skey mold. Of course, just cut a new die.
Would they? I doubt it. Atlantic Standard could have something to say about it.
Marion Co in Fl owns the HCE dies today, They could have something to say about it.

If they did, I think we could tell the difference. Ebay is another story.
